for(var i:Number=0; i < 4; i++){
var child:comp_DG = new
comp_DG();
myTab.addChild(child);
child.arrColInfo = arrCol;
child.myLBL.text = ''+i;
child.label=''+i;
}
If i understood correctly your problem - when changing anything on any
one of the datagrid, also replicates the same change for rest og the
three datagrids and that is the problem ..... Correct?
In that case it might be because you are assigning same instance of
arrCol to every child object. You may consider creating clones of
arrCol object and assign to eacg child.arrColInfo.
